5 C API

This chapter contains a description of all modules and a
list of all documented C functions in the program. It contains
many references and is self-generated from C comments using
gdoc by Simon Josefsson.

In order to reduce the number of pages of printed output, this complete reference
is, by default, disabled in printable versions of the documentation (PostScript, PDF).
This is both to make the manual more readable and to avoid wasting paper.
Think about the environment.
